4 3. Factory Inspection An (initial) inspection of the production plant is to be carried out as part of the certification process. 4. Surveillance Monitoring checks are to be carried out once a year on selected PUR foam samples to manage or extend the certificate or alternatively a new inspection of the production plant is required. A monitoring check can take the form of a partial test using selected parameters. The number of articles to be tested is coupled to the number of certified PUR foams. 5. Sampling, Packaging and Shipping A foam sample, size approx. 60 cm x 60 cm x 15 cm, has to be cut out of the foam block according to the TRLP () sampling record. Deviating dimensions must be justified and explained. The test sample has to be packed within seven days after foaming. The test sample must be packed tightly wrapped immediately after production (in aluminium foil that is additionally protected by an air-sealed plastic bag, polyethylene foil or similar). The following has to be recorded: Exact designation of the foam, Batch No., foaming date and packing date. The test sample has to arrive at TRLP within 7 days after the test sample has been packed. 6. Manufacturer's Information For the purposes of certification the applicant must send details of all materials built in or used, including all alternative suppliers (materials list). In a Manufacturer s Declaration the manufacturer confirms that no halogenated plastics (e.g. PVC) or halogenated flame retardants or any of the compounds named below have been used as structural components. Page 4 of 6

5 Note All materials used must meet the statutory requirements (e.g. of the Chemicals Prohibition Ordinance, ChemVerbotsV). It is not permissible to use halogenated plastics (e.g. PVC) or halogenated flame retardants either in the foam or in its packaging. The following are not permissible as constitutional components: - CMR substances as per Index 2 (Page 6): CMR = carcinogen (C), mutagen (M), reprotoxicant (R) under EC classification as per Annex VI of EC Regulation No. 1272/2008 (GHS) or national classification as per TRGS 905 or MAK and BAT value list of the German Research Foundation (Categories 1 and 2 and Pregnancy Groups A and B). - Substances classified in Annex VI of EC Regulation No. 1272/2008 (GHS) as inhalant allergens (Category 1) and skin allergens (Category 1) or in TRGS 907 or MAK and BAT value lists as sensitising. - Substances that, according to the criteria of Annex XIII of EC Regulation No. 1907/2006 are persistent, bioaccumulative and toxic or very persistent, very bioaccumulative and very toxic, identified as such or are already included in Annex XIV of the aforementioned Regulation (SVHC, Substances of Very High Concern, Isocyanates are not included due to technical requirements. - Phthalates, which are limited under EC Regulation No. 1907/2006/EC (refer to Point 2.3) or were identified as SVHC. TRLP must be notified of any changes in the materials used (e.g. foams, textiles, adhesives), including changes of supplier. In the event of a change of component or a change of supplier, the certified product might have to be retested. A materials list must be completed for the initial inspection and made available to TRLP. Page 5 of 6

6 Annex to Indices to 1. Emission Testing and 2. Material Testing: 1 VOC = volatile organic compounds 2 CMR = carcinogen (C), mutagen (M), reprotoxicant (R) under EC classification as per Annex VI of EC Regulation No. 1272/2008 (GHS) or national classification as per TRGS 905 or MAK and BAT value lists of the German Research Foundation (Categories 1 and 2 and Pregnancy Groups A and B). 3 Substances classified as acutely toxic and specific target organ toxic in Annex VI of EC Regulation No. 1272/2008 (GHS) or as highly poisonous (T+) or poisonous (T) under 3 Points 6. and 7. of the Ordinance on Hazardous Substances (GefStoffV). The CMR substances listed under Index 2 and the substances listed individually are not included since these are already limited. 4 The substances listed under Indices 2 and 3 and the individually listed substances are not included since these are already limited. 5 TVOC: total volatile organic compounds 6 TSVOC: total semi volatile organic compounds 7 It is permissible to exceed the guideline value for volatile organic compounds up to 150 µg/m³ if the exceedance is solely caused by siloxanes. The limit value of 650 µg/m³ including siloxanes may not be exceeded after 7 days of conditioning. For baby items (children's mattresses) this exceedance is not permissible. 8 In forming the corresponding totals, all individually quantified components are included with a test chamber concentration of 1 µg/m³. Insofar as possible concentrations of all individual compounds are quantified against authentic standard. Unidentified substances are quantified on basis of substance groups against substance-like compounds from this group. 9 R-value = total of all R i -values (R = C i / LIC i, Lowest Concentration of Interest). The R-value is based upon a model indoor air room analysis and is used here as a guide valuation of the test chamber concentrations. 10 Total of butyltin, tetrabutyltin, octyltin, dioctyltin, tricyclohexyltin and triphenyltin 11 Di-iso-hexylphthalates (DIHexP), Di-iso-heptylphthalates (DIHeP), Di-iso-octylphthalates (DIOP), Di-iso-undecylphthalates (DIUP), Di-n-hexylphthalate, Di-n-heptylphthalate, Di-n-nonylphthalate, Di-n-decylphthalate, Di-n-undecylphthalate Page 6 of 6
